Perma-Coil Products

Perma-Coil helically coiled inserts are made of stainless steel wire that has been rolled to a carefully controlled thread form. When installed, Perma-Coil inserts adjust to a tapped hole, becoming a functional thread with a strength exceeding the original.

Perma-Coil inserts and repair kits are designed to repair stripped threads in a variety of metals, including aluminum, aluminum alloys, steel, and cast iron. If the original threads can be stripped, Perma-Coil inserts can repair them. 

We offer a complete line of Perma-Coil products, including metric and inch inserts, complete kits, and spark plug repair kits. For more information on pricing, availability, or the right thread repair kit for your needs, please give us a call.
